A pickup truck's weight depends on the model, make and size of the truck. Normally, a pickup truck would weigh from 1750 lbs to 4550 lbs, but even that is just a guess since the exact numbers vary from one truck to the next. A pickup truck's weight depends on the model, make and size of the truck.
rods and cones. The photoreceptor cells of the retina. They are between the pigment epithelium and the bipolar layer of neurons. The rods contain rhodopsin, which is stimulated by light; the cones contain one of three other photopigments, which are stimulated by various wavelengths of visible light (colors).
Cats, like humans, have both rods and cones in the retina. Rods are the receptors that the eye uses for night time viewing and sudden movement. Cones are used during the daytime, and process color information. Cats have more rods than cones, as compared with humans, making cat night vision superior to humans.
